The renewed interest in plant proteins has stimulated research aimed at developing markers to aid in the selection of legume varieties better adapted to nutritional needs. Among the traits to be improved and stabilized is the amino acid balance of seeds, the essential amino acids methionine and tryptophan being particularly under-represented in legume seeds. This thesis focuses on seed protein composition, which is a major determinant of the seed amino acid balance. The objective was to explore the genetic and environmental variability in this trait and to identify genes potentially involved in its plasticity when subjected to environmental stresses. In the first part of the thesis, the pro…
MOOC : "ProtéiNNOV : Protéines végétales et Innovation"
2018
La prise de conscience d'une raréfaction des ressources en protéines animales dans les décennies à venir et la nécessité de produire plus durablement ces ressources alimentaires nous conduit à repenser aux autres sources de protéines, notamment les protéines d'origine végétale. Parmi les sources de protéines végétales, la plus employée comme substitut des protéines animales est le soja, mais le soja n'est pas la seule source de protéines végétales. Il est donc opportun de faire le point sur les autres sources de protéines végétales et sur leur utilisation. Le développement de nouveaux produits alimentaires riches en protéines végétales passe par la connaissance des atouts tant technologique…
Rbt1 Protein Domains Analysis in Candida albicans Brings Insights into Hyphal Surface Modifications and Rbt1 Potential Role during Adhesion and Biofi…
2013
Cell wall proteins are central to the virulence of Candida albicans. Hwp1, Hwp2 and Rbt1 form a family of hypha-associated cell surface proteins. Hwp1 and Hwp2 have been involved in adhesion and other virulence traits but Rbt1 is still poorly characterized. To assess the role of Rbt1 in the interaction of C. albicans with biotic and abiotic surfaces independently of its morphological state, heterologous expression and promoter swap strategies were applied. The N-terminal domain with features typical of the Flo11 superfamily was found to be essential for adhesiveness to polystyrene through an increase in cell surface hydrophobicity. A 42 amino acid-long domain localized in the central part o…
Legumes in 21st century Europe: present and future importance in agri-food systems? New challenges for reseach.
2013
Intensification of agriculture since 1950 has globally led to the decline of grain legume crops, which currently represent less than 3 % of arable crops in France and Europe. Nevertheless, legumes have several major assets (i) as plant proteins for animal feed and human food and (ii) as plants fixing atmospheric N2 and thereby saving nitrogen inputs in cropping systems, and (iii) as diversification crops. The analysis of forage and grain legume producing systems in France showed that the dominant system results in a lock-in of the different factors limiting legume insertion into the current systems. But legumes could have a major role to play in the agroecological transition towards more su…
